Message: [QUOTE="TARM, post: 79986, member: 578"] A few things: I can not see any real benefits to dual sump for the dual pumps. Beyond that you will now have two hose and fittings hanging low asking to get tore off and dump your whole tank before you can get out of the truck. Same goes for cutting into the poly tank in two places on the same end or side. More chance of leaks and weakness. A 5/8 hose and fitting will flow so much more fuel than you could ever dream of using and way way more than those two pumps will ever need. I do not know the internal specs of the 6.0 pumps. Check if they have check ball or valves on the outlets. If not you need them. Not only to prevent loop back during a failure but it can help flow balance and reduce pressure pulses. Consider the placement of some cut off valves to allow for mess free filter changes. When looking at your final filter make sure to notice what the filter micron rating is for. Nominal, Absolute, single or multi pass? Most accurate numbers will be its actual beta ratio. You want as close to 2 mics and 99.98% as possible but with proper flow rate capacity. Take the WIX NAPA listed on the chart they only have a total of 5mic nominal (50% per pass). That could be 8 absolute not sure but its sure not 5 or below. Most pumps list their maximum flow rates @ free flow or zero psi outlet pressure and no inlet vacuum. Maximum working pressure usually is at a significantly reduced flow rate compared to its maximum or free flow rate. I am not sure how they are attaining there max flow and pressure rates on that chart. But a 4 bar maximum operating pressure is only 58 psig Consider the maximum for the 7.3 pumps is 100 psi or almost 7 bar. But I assume this is going on a 6.0 Liter Kind of had me thrown with it being in the 7.3 forum. It maybe that 6.0 do not need the flow pressure 7.3s run with larger injectors. Maybe thats the flow rate at that pressure in which case is plenty. With the braided hose pick up some rolls of clear heat shrink tube. The thicker kind works well. You can slide that over the SS braided hose before you install the hose ends. That will address rubbing wear SS. Looks great but smooth. [/QUOTE]
